To all whom z't may concer/lt.'

' Be it known that I, BARTLETT ARKELL, a citizen of the United States,residing in the borough of Manhattan, city, county, and State of NewYork, have invented certain new and useful Improvements in Machines forMaking Stretchable Crinkled Paper, of which the following is a full,clear', and exact description.

This invention relates to a machine for making stretchable' crinkledpaper of the type that is used for packing and wrapping purposes.

In the manufacture of crinkled paper it is desirable that the paper bemoistened before it is placed on the receiving roll and acted upon bythe doctor to form the crinkles in the paper. After the paper hasreceived these crinkles, it must again be dried and in such a mannerthat the crinkles are not destroyed during the drying. The dryingprocess requires a Iconsiderable amount of heat and renders the roomsmore or less uncomfortable.

It is an object of this invention to condition the paper while inltheweb for being placed upon the receiving roll so that it may becrinkled by the doctor with a minimum amount of moisture content. By soreducing the moisture content less heating will be required tosubsequently dry the crinkled paper.l

Another object of my invention is to subject the paper while in the webto successive wetting and squeezing operations, so that the moisturewill be compelled to permeate all parts of the web.

Other objects of the invention will appear as the description proceeds.

In the drawings, wherein I have shown three of the many possibleembodiments of my invention,

Figure 1 is an elevation of the machine showing the essential parts ofthe completed machine;

Fig. 2 is a section taken on plane 22 of Fig. l;

Fig. 3 is an elevational view of a machine modified from what is shownin Fig. 1 and showing but one of the wetting and squeez-l ing devices;and

Fig. 4 is a view similar to F ig. 3 showing a further modified form.

According to the form of the invention, as shown in Figs, 1 and 2, amain frame 5 kbe adjusted.

carries at one end a suitable supporting bracket 6 for the roll 7 offinished paper from which it is fed while in the web as at 8 to thevarious parts of the machine.

Also mounted on this frame is a tank or receptacle 9 adapted to containa bath 10. In this bath a plurality of immersing rolls. 11 .are carried,these rolls being submerged in the bath 10. On the top ofthe frame andover the tank 9, a plurality of squeezing devices are located. Thesesqueezing devices 12 comprise a fixed rubber-faced roll 13 and anadjustable rubber-faced roll 14 mounted in suitable boxes 15 andprovided with compressible springs 16 and hand wheels 17 whereby thepressure between the rolls may The first roll at the left, as shown inFig. 1, is preferably placed substantially so that its axis is locateddirectly above the axes of the immersing rolls 11 and halfway betweenthem. In the form shown, three sets of immersing rolls 11 and three setsof squeezing devices 12 are shown. I do not intend to limit myself tothree such devices, for I mav use more or less as conditions require,and I may not use all of the devices on a machine at all times. j

lAt the opposite endof the frame 5. a power shaft 18 is mounted, whichcarries a suitable driving pulley 19 at one end, and another drivingpulley 20 on the opposite end. A belt passes over the pulley 20 andabout a suitable pulley arranged at one end of one of the squeezlngrolls. As shown, it connects with a pulley 21 carried on the back sideof the right hand squeezing `device. Another pulley 22 is carried on thefront side of the first squeezing device. The other two squeezingdevices carry the same sized pulleys and are driven by the belts 23 and24 as shown. i

Also driven from the shaft 18 is a receiving roll 25 and: associatedwith this re ceiving roll is the doctor blade 26 which crinkles thepaper as it is driven against it. Near the receiving roll 25 anadjustable pressure roll 27 is also carried by the main frame.

The web 8 of paper, as it oomesfrom the roll 7, is directed over a.roller 28 and under the left immersing rollll. It then goes upwardly andabout the lower roll 13 of the left side of squeezing devices, whereany' excess moisture will be expelled and where the moisture will beforced through the squeezing device the paper is fed under the v nextimmersing roll 1l. rlFhe paper is passed from this immersing rollthrough the next squeezing and immersing rolls which act in successionon it. t

The main driving belt 29, acting on pulley 19, draws the paper throughthe machine and as it passes it about the rece1ving roll and against thedoctor blade 26, the paper is taken off the receiving roll in a crinkledcondition.

According to the modification of the in.

vention shown in Fig. 3, the web 8 of paper is passed between two pipeswhich carry water under pressure, the pipes having suitable holes 31therein so that the water is forced out in the form of a light sprayagainst the paper from both sides. The wetted sheet is then passedthrough squeezing devices 12 similar to the squeezing` devices l2 beforedescribed. rlhe drawing shows but one set of wetting and squeezingdevices, but it is understood that a plurality of each of these iscontemplated, and that the paper will pass through them in succession.

According to the modification shown in Fig. 4, the web 8 is wetted bybeing passed between rollers 32 and 33. The roll 33 has a feltcovering'i, and is supplied from the interior 35 through perforations 35with water to wet the felt. rllhe wetted felt will then dampen the paperas it is passed through. Similar squeezing devices 12 are used asbefore, and a plurality of wetting and squeezing devices iscontemplated.

For some qualities and weights of paper more immersing and squeezingoperations will be necessary than for other types of paper, and in thecase of paper requiring fewer wettings and squeezings than the machineis capable of applying, the web may be directed so that it will not passabout. all the immersion rolls 11, that is, it might go directly fromroll 28 to the left squeezingl device l2, or fromV one squeezing devicedirect to the other.

The water or other liquid with which the paper is wet should be hot andpreferably near the boiling point as high temperature of the wettingliquid promotes penne-ation of the paper. lf desired, the pipes 30 inlFig. 3 may supply steamto wet the paper instead of water or otherliquid.

iVfhile lf have shown'the invention and its modifications in what lbelieve to'be the best and most efficient form, it will be understoodthat various changes may be made without departing from tlie scope ofthe invention.
